The purpose of this study was to establish the intra-rater and inter-rater reliability of isometric shoulder strength assessment using a hand-held dynamometer (HHD) in functional joint positions in student circus artists with symptomatic atraumatic shoulder instability.
Over two testing sessions, two experienced physiotherapists assessed the shoulder strength of 24 student circus artists with clinically diagnosed atraumatic shoulder instability. Both the symptomatic and asymptomatic shoulder was assessed using a HHD in 10 functional positions. Intra-class correlation coefficients (ICCs) were calculated to determine the reliability of strength measurements.
All examined positions showed moderate-high intra-rater and inter-rater reliability. External rotation at 0° and internal rotation in horizontal flexion at 45° revealed the most reliable results, and the shrug position the least reliable. Inter-rater and intra-rater reliability was high and demonstrated similar results in symptomatic and asymptomatic shoulders by both raters.
This study demonstrated clinical applicability in reliably measuring functional strength in symptomatic atraumatic instability or asymptomatic shoulders when assessed by experienced therapists using an HHD.
本研究的目的是在有症状的非创伤性肩不稳定的学生马戏艺术家的功能关节位置中，使用手持测力计（HHD）来确定等距肩部力量评估的组内和组间可靠性。
在两次测试过程中，两名经验丰富的物理治疗师使用 HHD 在 10 个功能位置评估了 24 名临床诊断为非创伤性肩不稳定的学生马戏艺术家的肩部力量。对有症状和无症状的肩部进行评估。使用组内相关系数（ICC）来确定力量测量的可靠性。
所有检查的位置均显示出中等高度的组内和组间可靠性。外旋在 0°和内旋在水平屈曲 45°时显示出最可靠的结果，耸肩位置最不可靠。两位评估者在有症状和无症状的肩部均表现出高度的组间和组内可靠性，并且结果相似。
本研究表明，当由经验丰富的治疗师使用 HHD 评估时，在有症状的非创伤性不稳定或无症状的肩部中，该研究具有可靠的功能性力量测量的临床适用性。
